Issue: The handler didnt handling correctly, when im texting 'adhewfg' or some random word, the bot return handler with specific text. My code looks like this:

@bot.message_handler(func=lambda message: "goBackProvider") # when i sent random word, the bot return message from this handler
def nextGuess(message):
    markup = types.ReplyKeyboardMarkup()
    btn1 = types.KeyboardButton(buyMLBB)
    btn2 = types.KeyboardButton(buyFF)
    btn3 = types.KeyboardButton(buyAOV)
    btn4 = types.KeyboardButton(buyPUBG)
    markup.add(btn1, btn2, btn3, btn4)
    bot.send_message(message.chat.id, "Silahkan memilih provider yang tersedia!", reply_markup=markup)

@bot.message_handler(func=lambda message: True) # my expectation is the bot return message from this handler
def what(message):
    bot.reply_to(message, 'Maaf, aku tidak mengerti maksud kamu, gunakan tombol/perintah untuk berinteraksi denganku')

did i forget something?

func=lambda message: "goBackProvider"

Lambda is wrong and always returns "True".

func=lambda mess: mess.text == "goBackProvider"
