There are many different motivations for playing poker.
Some play for the ego - they like to win pots and they don't care about the size of the pots they win, they just want to win.
Some play so they can bully people - they don't care about pot odds or equity or anything like that - they just like raising.
Some play to pass the time - they don't care about winning, as long as they get a good amount of playing time for their money. Winning is a lucky bonus.
Some play for the thrill of gambling - they like to build big pots with draws because they enjoy sucking out - the bigger the pot and the longer the odds against them the better.
And so on.
Don't worry about them. As long as they're happy to keep bringing chips to the table, they're welcome
